Image Resizer — frequently asked questions
How do I keep the proportions?
Keep “lock aspect ratio” on, so changing one dimension updates the other.
Will resizing reduce quality?
Making an image smaller keeps it sharp; enlarging a small image can look soft.
What size should I use for the web?
Match the largest size it will display at, often 1200–1600 px wide for full-width images.
